- How can I have more than two command line flags control the same behavior?
- In Go, I know how to use the github.com/pborman/getopt package to perform getopt-like command line parsing. However, this package seems to only support one string version and one rune version of each command line option. Sometimes I want more than just two ways to specify options. For example, for a hypothetical program called prog, I would like the following code to all perform the exact same function: prog-r[otherargs]prog-r[otherargs]prog--recurse[otherargs]prog--recursive[otherargs]

- Detailed explanation of Linux program compilation process
- Computer programming languages are usually divided into three categories: machine language, assembly language and high-level language. High-level languages need to be translated into machine language before they can be executed. There are two ways of translation, one is compiled and the other is interpreted. Therefore, we basically divide high-level languages into two categories, one is compiled language, such as C, C++, Java, and the other is interpreted language, such as Python, Ruby, MATLAB, and JavaScript. This article will introduce the process of converting high-level programs written in C/C++ language into binary codes that can be executed by the processor, including four steps: Preprocessing (Preprocessing) Compilation (Compilation) Assembly (Assem)

- Linux Penetration Testing Tutorial: Teach you step-by-step on stack overflow from getting started to giving up
- For the content of the notes, refer to the KaliLinux penetration testing tutorial by Mr. Fanghong from the Security Niu Classroom. The crux of all vulnerabilities comes from data input. The principle of buffer overflow is that the boundary between data and code is blurred. When the buffer boundary limit is not strict, because the variable transfer Entering malformed data or running the program incorrectly causes the buffer to be "exploded", thereby overwriting the data in the adjacent video memory area. Successfully changing the video memory data can lead to process kidnapping, execution of malicious code, and acquisition of server control. To better understand the principle of buffer overflow, refer to the article reprinted by the author: Teach you step by step about stack overflow from getting started to abandoning it (Part 1) Teach you step by step about stack overflow from getting started to abandoning it (Part 2) Article Table of Contents 1.
